Free, no-signup summaries of PDFs and 13 other document formats, with follow-up chat.
PDF Summarizer is a free web tool that reads an uploaded document and returns a summary, without requiring an account. It handles PDFs plus 13 other formats including DOCX, PPTX, XLSX, TXT, EPUB, and image files, up to 50MB per file, and can process lengthy documents without the user manually splitting them into chunks. Beyond the initial summary, the tool supports a chat interface for asking follow-up questions about the document, and lets users adjust summary length and focus. Output and input can be in different languages. The site publishes no company name beyond the domain itself and no traditional about page, only a copyright line and a link to an unrelated site in the footer.
Free with no registration; the site states unlimited summaries with no hidden limits.
Use tool ↗PDF Summarizer does one thing without friction: upload a document, get a summary, ask follow-up questions, no account needed. The 14-format support and 50MB cap cover most real-world documents, and the lack of a signup wall makes it fast to actually use. The tradeoff is that there's no company information anywhere on the site, so there's no way to judge who is processing the uploaded documents or how long they might be retained.
Watch out: No data-handling or retention policy is visible on the site, so avoid uploading sensitive or confidential documents.
